fix(ci): restore allowBuilds map in pnpm-workspace.yaml

pnpm 11.x reads the per-package allowBuilds boolean map, not the
pnpm 10 onlyBuiltDependencies arrays. The array form is silently
ignored, so every build script falls through as 'ignored' and
strict CI mode fails. Confirmed by reproducing locally and by
inspecting what 'pnpm approve-builds --all' writes back.
